Here’s some advice from someone with an environment where we have folders containing tens of millions of files. A folder stores the index information (links to child files & child folder) in an index file. This file will get very large when you have a lot of children. Note that it doesn’t distinguish between a … Read more
Microsoft distributes at least two Sysinternals tools for this. Junction lets you manipulate junction points (symbolic links). Streams will show you alternate data streams. That page also shows you the :stream syntax to manipulate them from command-line.
When I’ve seen this it was because a process was holding the folder open but the folder was in the process of being deleted. Use a tool like Process Explorer to see if anything has an open handle on the folder. I would guess that once you release it or reboot, that folder will disappear.
Individual components of a filename (i.e. each subdirectory along the path, and the final filename) are limited to 255 characters, and the total path length is limited to approximately 32,000 characters. However, on Windows, you can’t exceed MAX_PATH value (259 characters for files, 248 for folders). See http://msdn.microsoft.com/en-us/library/aa365247.aspx for full details.
Even assuming you meant GBps and not Gbps… I am unaware of any filesystem that has an actual throughput limit. Filesystems are simply structures around how to store and retrieve files. They use metadata, structure, naming conventions, security conventions, etc. but the actual throughput limitations are defined by the underlying hardware itself (typically a combination … Read more
They’re identical – both use ntfs-3g in (current) Ubuntu; the ntfs utils are just symlinked to ntfs-3g. # which mount.ntfs /sbin/mount.ntfs # which mount.ntfs-3g /sbin/mount.ntfs-3g # ls /sbin/mount.ntfs* -l lrwxrwxrwx 1 root root 13 2011-03-01 21:13 /sbin/mount.ntfs -> mount.ntfs-3g lrwxrwxrwx 1 root root 12 2011-03-01 21:13 /sbin/mount.ntfs-3g -> /bin/ntfs-3g
My approach is to not use file/directory level file permissions; use file share level permissions, and set the whole server filesystem data drive to Everyone Full Control (which becomes moot). Over the years (10+), I have found that NTFS permissions are more complex and leads to more errors. If the permissions are set wrong, or … Read more
subinacl is a Windows sysadmin’s power tool for doing everything to do with ownership and ACLs. You can change the ownership to anyone other than just you (you can’t do this with the GUI). subinacl /file test.txt /setowner=domain\foo This lets you set the permission to any user you like, without having to be an administrator … Read more
The methods are there, but until Microsoft re-codes the file-browser widget we’re pretty much stuck with that old problem. It’s sub-optimal, but that’s just how it works.
I’d recommend using a regular file system instead of databases. Using file system is easier than a database, you can use normal tools to access files, file systems are designed for this kind of usage etc. NTFS should work just fine as a storage system. Do not store the actual path to database. Better to … Read more
